Adsorption
modifying of solids with aqueous solutions of derivatives of fullerene C60
containing of maleimide and dipeptide addendes
Abstract
The
regularities of adsorption modifying of different solid surfaces with aqueous
solutions of fullerene C60 derivatives (FD) containing maleimide and
dipeptide addends were studied by quartz crystal microbalance method and
contact angle measurements. In spite of the absence of surface activity at the
solution-vapor interface the high adsorption activity of FD at the solution-solid
interface was founded. With respect to high energy solids the FD behavior are
similar to one for ionic surfactants with polar groups charged opposite to
solid. The adsorption modifying of polymer surfaces leads to its
hydrophilization so as classic low-molecular surfactants. The highest modifying
effect with respect to high- and low energy solids is observed for FD with
least solubility in aqueous phase.
Key words: fullerene C60
derivatives, adsorption, wetting, quartz
crystal microbalance.
